Definition of an automatic selection list

I want a certain column, every time I click on a row in this column I will activate this setting, it will work automatically
Namely:

For example, if I enter 3 words or numbers in 3 lines with alt+down, it gives a selection list giving you what is above

I want each automatic line to give only from a selection list only and not to write down what you want

Prefer a definition for each and every row separately

It is not enough the built-in Autocomplete function for you?

Or you can use the Data validity feature. Use “Cell range” from the target range for the selection list.

Regarding your question, is it not enough for me?
Indeed, I want it to be structured, I can send you an Excel file that is structured like this

And regarding the downloadable file if you could send it to Google Drive with a link here it would be helpful because the security filter I have on the internet prevents me from downloading it
